To ail whom it may-concern iile it lrnown that l, Nana H. Nansen, acitiaenof the United States, of Willmar, Kandiyohi county, Minnesota,have invented certain new and useful Improvements in Traotiondhlngines,of which the following is a specification.

The object of the invention is to provide a traction engine adapted foruse for'all lrinds of farraworltand a further and particular object isto provide a traction engine which may housed for drawing a cultivatorthrough a field corn, the machine stradtiling one or more rows withoutdanger of breaking the corn stalks.

A further object of the invention is to rovide a traction enginewhichwill read- My adapt itself to an uneven surface without racking ortwisting the frame of the machine or the operating mechanism thereof,and a still further object is to provide a comparatively light machineand one which will bestrong and durable and of suflicient power for allkinds of work on the farm.

My invention consists generally in various constructions andcombinations, all as hereinafter described and particularly pointed outin the claims. 7

In the accompanying drawings forming part of this specification, Figure1 is a plan view of a traction engine embodying my invention, thetransmission gearing casin being removed to show the position, o" thegears therein, Fig. 2 is a transverse sectional view of the engine. Fig.3 is a detail view showing the equalizing bar and its connection withthe wheels to adapt the machine for an uneven surface, Fig. 4: is asectional view of the rear wheels.

In the drawing, 2 represents the frame of the 5 machine, 3 the reartraction wheels mounted on an axle 4; having a raised or ofi'set portionbetween the wheels and whereto the side bars of the frame are secured. 5is a platform at the rear of the frame between the rear wheels and 6 adraft bar ex tending transversely of the machine and to which theagricultural implements are attached in the ordinary manner.

' 7 and 8 are engines located upon 0 posite sides of the longitudinalcenter of the ma chine, preferably directly in front of the reartraction wheels. is interposed between these engines and has clutchconnections 10 therewith sothat the A transverse shaft 9' shaft may beoperated from either one or both of the engines. [a pulley 11 isprovided outside the engines on each side of the machine from whichbelts may be run to a separator or any other machine which it may bedesired to operate on the farm. A. sleeve 12 is splined on the shaft 9and carries a pinion l3 and has a clutch 1d. The pinion '13 is adaptedto mesh with a gear 15 of the transmission gearing; that is mounted inthe gear casing 16. It being; of ordinary construction, 1 will make noclaim to the same herein except to state that the train of gearstransmits power from the engine to a gear 18 mounted on a shaft 19having driving connections, (not shown) with the rear tract-ion wheelsof the machine.

By means of the clutch 14 both engines may be opcratively connected withthe shaft 19 to drive the machine and by means of the clutches 10 eitherone or both of the engines may be utilized to drive the machine, or oneengine may be used to drive the machine and the other one belted to aseparator or other machine. The clutches are controlled by suitablelevers 22 mounted at the rear of the machine near the drivers seat 23. Iprefer also to connect the shaft 9 through the belts .24 with acoolingmechanism 25 disposed on the forward portion of the frame. This,however, forms no part of the suhjcct-matter of my invention anddetailed description is unnecessary.

Referring to Figs. 2 and 3, 26 represents cross bars connecting the sidebars of the frame and 27 is an equalizing bar or rocker pivoted at 28and adapted to rock vertically etween the bars 26, as shownin Fl 3. 1and 3. Hangers 29 are secured to the ame on each side and dependvertically to a point below the hubs of the forward wheels 30. Rods 31are jourualed in boxes 32 on these hangers and are adapted to slidevertically and rotate a limited distance therein. The forward wheelaxles 33 are mounted on these rods, (see Fig. 2) and move up and downwith the rods and swing with the rotation of the rods. The upper ends ofthe rods have collars 34 thereon upon which the rounded or curved undersurface 35 of the ends of the equalizing bar 27 are adapted to rest, theequalizing bar having forked ends to straddle the upper ends of therods. The lower portions of the hangers 29 are braced and strengthenedby brackets 36 which are secured at their lower ends to the hangers andat their upper ends to the cross bar 26. It will be evident from anexamination of Fig. 2 that the space between the forward wheels of themachine will be practically unobstructed and the equalizing bar normallynear the ground line will be raised to such a distance from the groundthat the frame of the machine and the equalizing bar supported therebywill readilypass over one or two rows of corn without danger ofcontacting with the stalks and breaking them. In case one of the wheelsstrikes an obstruction or an uneven place in' the field, the rodconnected therewith will slide vertically and allow the wheel toaccommodate itself to the uneven surface without tilting the frame ofthe machine from its normal horizontal position. (See Fig. 3).

For the purpose of steering the machine I mount an arm 37 on the upperend of one of the rods 31 and a rocker 38 on the other arm and connectthe arm 37 with one end of the rocker 38 by a pivoted rod 39. A. link 40connects the other arm of the rocker 38 with a cable 41 which passesaround and is adjustably attached to wheels 42 and 43. One

of these wheels is preferably located at the forward portion of themachine and the other at the rear portion, the rear wheel havcable 41will be moved back and forth, rocking'the arm 37 and the rocker 38 andswinging the forward wheels forward and backward to steer the machine.The axles of the forward wheels may be secured by suitable means totherods 31 or they may be formed integrally therewith, as preferred. Themachine is preferably covered by a suitable canopy 48 supported bystandards 49.

In the operationofthe machine, the driver will connect one or both ofthe engines with the driving shaft and apply the power to the reartract-ion wheels to move the machine across the field. The oppositelyarranged engines will balance the frame of the machine, rendering itmore stable and distribut-. ing the load more evenly between the wheels.At any time the engines may be disconnected from the driving shaft andone or both of them utilized for drivin a belt or swinging up a cable orfor any 0t er work for which a machine of this kind might be utilized ona farm.

I claim as my invention:--
